being shown on the lower die.

Be it known that 1, CHARLES LurrLnR, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Box-Binding Machines, of-

which the following is a full, clear, and exact description.

I This invention relates to machines for binding the corners of boxes with metallic strips. The invention consists more particularly of the mechanism for-feeding the metallic strip and guiding it to the forming and setting dies and to the means for severing the strip at the required length for use. The machine to which my improvements are applied comprehends a stationary anvil or lower die adapted to receive thereon the corner of a hex adjusted thereto after the manner of a saddle and an upper reoiproeating die having a ii-shaped groove adapted to straddle the corner of the box and the rid go of the lower die and provided with means for holding a section of the metallic binding-strip until it is carried. down upon the corner of the box and fastened thereto by the force of the blow against the lower die.

The invention will be described-in detail with reference to the accompanying drawings, in which- Figure 1 is a side elevation of the machine, the lower portion of the base or sta udard upon which it is mounted being removed. Fig. 2 is a front elevation of the machine' Fig. 3 is an end view of a movable guide for the strip. Fig. l is an end view in detail of. the upper and lower dies, the corner of the box Fig. 5 shows the corner of the box after the metallic strip has been applied thereto. Fig. 6 is a side view of the feeding-wheel and lhe strip. Fig. 7 is a section takenv on line X X of Fig. 1. Fig. 8 is a plan of a portion of the strip, and Fig. 9 shows a box with the metallic corners as applied thereto by the machine.

Referring to the drawings by letter, A represents the base or standard supporting the machine.

(t is a frame secured to the top of the base and having mounted in it transversely a fired axle or studli. Upon this stud the operating lover or trcadle'lis pivotally mounted.

- lower side of the bar,

The hub of the treadle carries an arm t, which connects by means of an adjustable link i.- with a toggle-lever 25 The toggle is con neoted with a reciprocating piston c, mounted in vertical guides in the frame, carrying at its lower end a die-head d. In the face of the die-head is fixed a hardened-steel bar d, having a ii-shaped groove cl formed in it, the sides of which are each provided with mooves d, partially formed by plates d, fixed to the as indicated in Fig. 4. Immediately below the die-head is an anvil e, having a wed ge-shaped ridge e, corresponding in angle to the V-shaped groove in the die above it. This anvil is adapted to receive the box and hold it while the metallic strip is being applied to its corners and therefore is made adjustable in length to accommodate different sizes of boxes by mounting it in guidewa-ys e in the frame. A suitable hand-wheel e and screw isprovided for locking it in any position.

The metallic strip or ribbon which is applied to the corners of boxes is shown in de tail in Figs. 4, 6, and 8 and is represented by the letter s. ing a row of formed by perforations .9 near to each edge, striking the metal through and leaving a bur or tooth s under each hole.; The strip thus prepared is wound upon a reel and mounted in a frame f at the back of the machine. g represents a transverse shaft mounted at the rear of the machine in the frame a and having rigidly fixed upon it afeeding-wheel 9, located midway between the two uprights constituting the frame a and provided-with two rows of sprocket-teeth 9 Immediately beneath this wheel is a small plate 72, carrying two pins 7t, which project into cavities formed in the frame and serve as vertical guides for the plate. Beneath the plate and located in a socket i "is a-spring 73 which bears continuously against the plate and tends to force it against the periphery. of"

The face of this plate has two lugs wheel g. it, between. which the wheel 9' turns. It also has two grooves 72?, through which the tworows or sprocket-teeth pass as the wheel rotates. The strip 5 leads from the reel between wheel g and plate h, and the sprocket-teeth of the wheel are arranged to take into the respective rows of holes a in the strip, while the It is merely a strip of tin hav- Too , is'plainly shown in Fig. 7.

burs or teeth on the under side of the strip pass through the grooves h in plate h. This It will now be understood that when the wheel 9 is rotated the strip 3 will be fed along the plate 7b, serving to hold the strip up against the wheel and make the feed positive. Upon the shaft g is a ratchet-wheelj, and adjoining the ratchetwheel and loose upon the same shaft is a pinion 70, having an arm k extending therefrom and carrying a pawl, which engages with the ratchet-wheel. The ratchet, )inion, and pawl are located outside of the frame of the machine, as shown in Figs. 1 and '7. A reciprocating rack-bar Z, engaging with the pinion,

is mounted to slide through a box 1, bolted to the side of the frame, and is connected by means of a link on with the free end of arm 0, hung loosely upon the stud B, which projects through the frame a for that purpose. This arm is provided with a slot Immediately behind the arm is another arm 1), slotted or grooved similarly to arm 0. This arm p is fixed upon the end of a shaft 1),

mounted transversely in the two sides of the frame a. Between the two parts of the frame this shaft carries a crank 13 ,110 the end of which is pivoted a link 7, which in turn is connected with an arm 9 by means of a pin and slot, as shown, the arm 1" being a radial projection from the hub of theleverT. Arms 1) and o are pivoted together by means of an adjustable pivotand clamping-nut 13 Upon the arm p is slug 1), to which a spring pl, fastened at p, is connected for the purpose of swinging the arm in one direction. This lug p is provided with a shoulder 19 with which a pawl p is adapted to engage. This pawl is mounted on a shortrock-shaft 11", passing through one of the side pieces of the frame a and carrying a crank 1; inside of the frame, the end'of which is adapted to be struck by the lug q, formed on the hub of the operating-lever i. -When the arm 1) swings to the left to the limit of its stroke, the pawl drops behind the shoulderp and prevents any re-' turn movement of the arm until such time as lug q strikes the crank 11 andthrows the pawl out of engagement with the shoulder. The rack-bar Z carries a cross-head Z to limit its movement to the right.

Upon the rear of the die-head (l is fixed a block '11, provided with two vertical passages,- in which are fitted two rods-1t u, respectively, said rods being connected across the top by a bar it and across the bottom by platea, forming a rectangular frame adapted to slide vertically in the block. The downward movement of this frame through the block is limited by a set-nutu, and a spring a is arranged to force the frame to its lowest position. To thevunder side of.the plate u are fixed two brackets to u, having ledges around to support and guide the two edges, respectively, of the strip .9. \Vhen the die-head d is elevated and the rectangular frame a 1.6 a is at its lowest position, the passage of the strips through the brackets u is in a direct line with the grooves d in the bar (1. KVhen the die-head lowers and before it strikes the anvil, the brackets u strike a table 1: and the rectangular frame u n u is caused to slide through block u the die-head continues its movement downward. To the front edge of this table 'v is fixed a transverse knife-blade w, which, together with the rear edge or end of the bar (1, form a shears, the plane of cut being above the plane where the meeting.

surfaces of the die and anvil come together and coincident with the surface of table r.

The strip 3 after leaving the wheel 9 passes directly and unsupported to the passage in the brackets 11' and ends in the plane of the knife-blade. In the operation of the machine the treadle-lever T has a backward-and-return movement. As shown in the drawings, it is making its return movement, being impolled by a weight or spring. (Not shown.) The parts of the machine are shown in the position when the feeding of the strip to the die is just beginning. The pin in the end of lug -r engages with the end of the slot in the link q, moving the latter in the direction of the arrow, thus swinging the crank 19 and arm 1) in the same direction. By reason of the engagement between arms 1) and o the latter is caused to swing on its pivot B and pull rack-bar Z to the left. This rotates pinion k, and by reason of its engagement with shaft g, through the pawl and ratchet, wheel 9 is rotated in a direction to send the strip 8 forward, which it does a distance determined by the position of the pivot in the slots of the arms 0 and p. In thus feeding the end of the strip passes from the passage in brackets it into the passage or grooves d in the die. At the end of the feedingstroke pawl 13 drops behind the shoulder p and prevents any reaction or return movement of the feeding devices while the next step in the operation is taking place. The treadle T stops at the end of the feeding-stroke and is then returned to the right or to the rear by the foot of the operator. This movement carries the die-head d downward, the strip .9 moving with it until the brackets u strike table r, at which instantthe knife-blade comes in contact with the strip, and by the continued movement of the die-head the strip is severed, the cut-elf portion being carried downward onto the corner of the box, over which itis bent, and the teeth on the back of the strip forced into the converging sides of the box to hold the strip securely in place. \Vhile the die is thus proceedin g downward to do its work,the pin in the end bf arm 1" is traveling through the slot in the link q, and consequently imparting no motion thereto, but as soon as lug q on the hub strikes the crankp and throws pawl 11 out of engagement with shoulder 19 the sprin g 19 comes into play and carries arms 0 and p withtheir connections to the left, thus rotating the pinion in the reverse direction to its previous movement, the pawl slipping loosely over the 5o bindingstrip,

ratchet and the feeding-wheel 5 remaining stationary. As soon as the brackets a leave the table in the upward movement of the die-head, the pin in the end of the arm '1' again i strikes the end of the slot in link q and the i I strip commences to feed into the die, the feeding movement ending when the die head reaches the limit of its upward movement.

The strip is therefore being fed into the die I to while the latter is in motion.

It will be understood that the boxes oper- I ated upon by this kind of machine are usually made of pasteboard, and that the metallic strips applied thereto are intended to reinforce the corners. l

The boxes are handled by the operator of I the machine who saddles them upon the anvil and shifts from one corner to another between the strokes of the machine. F It is evident that the invention herein del scribed is as well adapted for a power-driven machine as for one operated by foot. Any skilled mechanic can make the necessary changes for operating the machine by power. Having thus described my invention, I l claim i l. Ina box-binding machine, the combination of a reciprocating die having a passage 5 for the binding-strip, a guide for the binding- 3o strip carried by said die and movable with l respect thereto, and a knife located between the die and guide for severing the strip as set forth.
